I love these "Best concert" threads. :)
Peter Frampton - twice. First time not long after Frampton Comes Alive had been out. He was great. I was 14 years old. Second time - roll the clock ahead 40 something years. The Farewell Finale Tour. Sept 2019 in Houston. Even better.
Skid Row/Pantera - Pantera opened up for Skid Row. Pantera kicked Skid Row's ass.
Lollapalooza 94 - all day show with some great bands. The Beasty Boys were great. As were George Clinton and the PFunk All Stars.
Rush - totally awesome.
Deep Purple - Great show
Night Ranger - Good times
Foghat - Hell yeah!
Hank Williams Jr. - He was great!
I could go on and on.
